coolant line bypass? I've noticed that the coolant bypass lines that you get with an LS6 intake block off the back lines. If you already have bypassed the throttle body couldn't you block off the front lines and radiator as well? Or do these lines serve some other purpose?
Thanks,

True that. True that.

Would it be possible to move the crossover to the rear and block off the front? Or does that link between the front crossover and radiator have to be there? Just trying to clean the bay up as much as possible and that TB bypass looks goofy.

It gets air out of the block and heads and lets it burp out of the radiator. Keep the line going to the radiator. One person posted here that he plugged the line and blew a freeze plug out of the head.

On a related note, when switching over from an LS1 intake to an LS6 there is a way to modify the old coolant line to use with the new intake without buying anything new right?
You can just cut and solder (or plug it up like in the pics int he link above) the open outlet shut on the front one but what would one do with the back part in order to plug it, still utilizing the old lines that is?

And on the front one, do you cut the 'Y' (or 'T') down right to the straighter part of it (leaving just the very top of the 'T') or leave a little tubing there as well? I would think some of the coolant would always get trapped in that little extra area as it crosses over it maybe, but then again that should matter I guess.
Thanks for the info.
